Abstract

The kinetics of thermal dehydration of Sr(HCOO)2·2(H, D)2O were investigated using a dynamic thermogravimetric technique. Differences were found when the hydrogen was partially substituted by deuterium. These differences were explained by means of a microscopic approach based on the static and dynamic microscopic properties.

Zusammenfassung

Die Kinetik der thermischen Dehydratisierung von Sr(HCOO)2·2(H, D)2O wurde mittels dynamischer Thermogravimetrie untersucht. Bei partieller Substitution von Wasserstoff durch Deuterium wurden Unterschiede gefunden, die durch eine auf den statischen und dynamischen mikroskopischen Eigenschaften beruhende Betrachtungsweise erklärt werden.

Резюме

Методом динамическо й ТГ исследована кине тика термической дегидра тации Sr(HCOO)2 · 2(H, D)2O. При частичном з амещении водорода на дейтерий обнаружены определенные различия, которые объ яснены на основе стат ических и динамических микрос копических свойств.
